摘　　要：针对网内采用了旁瓣匿影和旁瓣对消技术的脉冲压缩雷达,采用卷积噪声对该种雷达进行干扰。结合公式推导及仿真实验,验证了该噪声的假目标特性。同时得出了该噪声在雷达接收机处所能获得的匹配增益计算公式,在信号时宽分别为噪声时宽的5倍和10倍时,噪声在雷达接收机处分别能获得约7 d B和10 d B的增益,验证了这种噪声在分布式干扰中的功率优势。As to pulse compression radar within network radar which adopt side-lobe blanking and side-lobe cancellation, using convolution noise to make interference with it.Proving the false target feature of the noise by formula and simulation. Meanwhile, obtaining formula of matched gain that this kind of noise can get at receiver. When time wide of signal is 5 times or 10 times longer than time wide of noise, the noise will get about 7 dB or 10 dB of matched gain, which prove power advantage of this kind of noise.
